timc490310 4 Posted Thursday at 10:42 AM Share Posted Thursday at 10:42 AM I was changing the coolant on my newly acquired 2002 , only 7200 miles when I got it a couple weeks ago, and while getting the temp up to operating level I was looking at the rectifier and it was hot to touch. Is that normal ? It is the honda part, owner did not change anything except the recall on wiring up front. Thanks 1 Quote Link to post Share on other sites
Member Contributer mello dude 592 Posted Thursday at 01:00 PM Member Contributer Share Posted Thursday at 01:00 PM The OEM RR does run hot....... Quote Link to post Share on other sites
Member Contributer Dutchy 3165 Posted Thursday at 02:38 PM Member Contributer Share Posted Thursday at 02:38 PM It is designed to do that. The altenator/generator produces alternating current (Vac) that the RR converts to direct current (Vdc). The Ac output increases as the engine revs up; to some 75+Vac... The RR restricts to output to some ~14.4Vdc to stop your 12V battery getting FUBAR'ed. The excess current is "flamed off"..... ie converted into heat. Quote Link to post Share on other sites
Member Contributer ducnut 164 Posted Thursday at 03:39 PM Member Contributer Share Posted Thursday at 03:39 PM You’re best to install a Roadstercycle SH847 R/R Kit, ASAP. He offers an FH020 Kit, but, the SH847 is the one you want, as it’s Series circuitry and will help preserve your stator. The stator in your bike is a 1yr-only stator and no longer available from Honda. It’s worth the investment in the latest R/R technology to save what you have. Also, it’s advised to pull all the bodywork and go through every single connector, inspecting, cleaning, and applying something like Ox-Gard to them. I’d strongly consider going through the cooling system, replacing the thermostat, radiator cap, O-rings, and hoses (AS3 make a nice hose and clamp kit), swapping the fan blade to an outward blowing VTR blade, servicing the suspension, and flushing all the hydraulics. This will get all your regular maintenance and troublesome things out of the way. 1 Quote Link to post Share on other sites

Member Contributer Dutchy 3165 Posted Thursday at 07:23 PM Member Contributer Share Posted Thursday at 07:23 PM I strongly advise you to leave the coolant hoses and thermostat well alone if it ain't broke..... Quote Link to post Share on other sites
squirrelman 158 Posted Thursday at 11:09 PM Share Posted Thursday at 11:09 PM it it's not hot, it's not working. Quote Link to post Share on other sites
DannoXYZ 41 Posted Friday at 01:00 AM Share Posted Friday at 01:00 AM Yup, shunt-type RR dumps excess power not used to ground. It doesn't care how much is going where, total always come to 100% Quote Link to post Share on other sites
Member Contributer mello dude 592 Posted Friday at 02:05 AM Member Contributer Share Posted Friday at 02:05 AM At 7200 miles, he's got some time before it implodes on itself... Digital voltmeter anyone? Quote Link to post Share on other sites
Member Contributer ShipFixer 56 Posted Friday at 10:41 PM Member Contributer Share Posted Friday at 10:41 PM I'll just pile on with I just replaced the original R/R on my 2002, and the bike no longer smells like hot electrical wiring when it's running. Worth preventing future problems. 1 Quote Link to post Share on other sites
timc490310 4 Posted Saturday at 11:48 AM Author Share Posted Saturday at 11:48 AM ShipFixer, what did you replace your r/r with? Looking at the vfrness and sh847 Quote Link to post Share on other sites

Looking at the vfrness and sh847 Tim, if you are going to replace the R/R now, the sh847 is a good way to go, but skip the Vfrness... I have 6th gen mounting plate kits for that. 1 Quote Link to post Share on other sites
